The con'iposition in each tank is delivered therefrom under pressure andthe pressure in each to. l; is maintained by an 11-'l'.l-CO111-- prcssor.f? of any preferred construction. The compressors herein shown of thercciyn'ocstory type driven troni eccentrics 21 mounted upon the maindrive shaft 22 of the u'iochine which is driven from any suitable sourceof power through. a. drive pulley 23.

This pulley may he clutched to or unclutched from the drive shaft bymeans of the clu ch 24:. of any preterred type, which may he sotusted hylever :it one side ot the I113" chine and i'ror purposes of convenienceand quire e i nuin, each tnnl: is equipped with relie c valve 31 whichmay he by means of an adjusting screw 32 to blow oil at anypredetermined maximum pressure.

The composition is delivered under the requisite pressure from each tanknear the bottom thereof through a pipe line consisting of a verticalportion 33, a horizontal portion 34 and a vertical portion 35 to chamber36 (Fig. from whence it is discharged through the applying nozzle, whichwill be later explained. T he upright portion 33 of the lineterminatesat its upper end in a coupling member 37 which is supported uponabracket projecting laterally from the top The adjacent end oi thehorizontal portion of the line is equipped with a compuion couplingmember 39 and between two members I interpose a screen winch cleans thecomposition and prevents the -ivery of sediment or the like to thenozzle which might clog the same so as to shut or reduce the how of therequisite o unt of composition therefrom each deoperation. The couplingmember 39 is forced toward the memberiii' to clamp the meshed screenbetween these members by means of a clamping screw threaded through atapped boss l3 on the side of the topmember 12. The pipe line is alsopreferably equipped with shut-oil cock 4:4- by which the flow ofcomposition may be shut oil or regulated when desired.

Each tank is provided with stirrer or agitator carried by a verticalshaft 46 which is rotated by means of a large gear t? at its upper end,these gears being driven from a large driving gear 18 mounted upon theupper end 01": a vertical shalt {l9 which is equipped at its lower endwith a bevel gear 51 which meshes with and is driven by a bevel pinionon the drive shaft This drive shaft is provided at its left hand end,viewing Figs. 1 and '2, with a hand whee-1 53 by means of which themachine may be turned over by hand when occasion requires. Each of thegears a7 is adapted to drive reciprocatory can end feeding device whichconsists primarily of a slide member 5st mounted to reciprocate inguideways formed on the upper side of the top member 12, suitableunder-cut plates 55, 56, and 57 being bolteu to the upper side of thetop memberand undercut so as to overlie the edges or the slide members54 to retain these members in position during their reciprocatory movements. Each slide member 54 is pivotally connected by means of adepending stud 58 with a link or pitman which is connected at its otherend with its gear 47.

Referring to the gear and slide member shown at the right in Fig. 1:, itwill be ob served that the is provided with an upstanding pivotal stud59 and connection is estab ishcd between the stud 59 and the stud 58through a pitman 61 which comprises two pivotally connected jaws, themovable one 62 of which is urged toward the other jaw by a spring 63interposed between this j aw and the head of a bolt 64 passing throughthe movable j aw and threaded into the stationary j aw. Each of the,jaws is equipped near its end with a semi-circular recess or socket sothat the stud 59 is embraced by the two jaws, establishing thereby adriving connection between the gear and its slide member 54. Shouldexcessive strain be imposed upon the slide member by a jam resultingfrom an imperfectly formed can end or from other causes, the spring 63will yield under the excessive strain permitting the jaws to separateand release from the stud 59, thereiy breaking the driving connectionand per- .11 the slide member to stop so that no injury to the machinewill result. This connectionma-y also be disconnected will. in case itshould be desirable to operate one oi" the slide members only, and whenthis connection is released the slide member at the right of the machinewill remain stationary while the other slide member will continue tooperate.

A releasable driving connection b ween the other gear t? and its slidemember is also provided but this connection is adapt ed to automaticallyire-establish or reconnect itself without the necessity oi? manualconnection. The driving pitman 65, in. this instance, pivoted to thestud 58 at end and to an upwardly projecting stud G6 at its other endthe pitn'ian being of rigid construction. The stud 66 is mounted on adisk G? moun ed concentrically with the gear 47 but struc rallyindependent thereof.

it. sprii'ig-prcssed plunger 68 mounted in a rac- 1 socket 69 in thedisk 67 is normally urged outwardly into engagement with a socket 71formed on the inner periphery the gear wheel 47. The outer end ot thepin 68 is rounded, as shown in Fig. 1, and wh n excessive strain isimposed. on the slide in her the pin 68 will be forced inwardly againstthe tension of its spring so as to re lease from its socket 71, therebypermittin the disk 67 to stand still while the gear revolves. Each timethe socket 71 is brought into alignment with the plunger 68 the plungerwill be projected into this soclret and after the obstruction to theslide member St has been removed the driving connection will beautomatically reestablished but so long as opposition to movement of theslide member is excessive the plunger will not permanently engage withits socket and the disk 67 will remain motionless while the gearcontinues to revolve.

The slide members 5-1- are adapted to con- Vey can ends from themagazines to compo sition applying stations and from the sta tions to adelivery point at the rear of he machine. Above each slide member thereis mounted a magazine adapted to contain can ends in stacked relation.These magazines consist each of a plate 72 mounted upon the top of themachine and carrying vertically disposed posts 7 3 between which the canends 7st (Figs. 6 and 7*) are stacked. Each slide'member is bifurcatedfor some distance from its rear end, providing a space between thebifurcations of greater width than the diameter of the can ends to befed, and at the forward ends of these bifurcations a shoulder tarsformed where the bifurcations merge into the slide member proper, which,when the slide member is in its extreme forward position, as shown atthe left in Fig. 1, will. be disposed forwardly ofthe magazine so thata. can end in the magazine will drop down back of the shoulder. Theextremities of the bifurcated portion of the slide members are turnedinwardly, as indicated at 76, so that the distance between them is lessthan the diameter of the can ends to be operated upon. When a can end inthemagazine has been positioned in front of the shoulder 75, as shown atthe left of Fig. 3., upon rearward movement of the slide member to theposition of the one shown at the right in Fig. 1, this lowermost can endwill be carried rearwardly a distance equal to the length of stroke ofthe slide member. Vi hen this distance has been traversed the can endhas been positioned at the composition applying station and directlyover a chuclr head 77 mounted upon a rotatable and verticallyreciprocable spindle 7 8 which is guided in its movements in a bearing 79 attached to the body of the machine, as shown in Fig. ,1. This chuckhead is normally maintained in its lower position, as shown in Figs. iand by an expansion spring 81 surrounding the spindle and disposedbetween the lower end of the bearing Y9, and a washer 82 secured to thelower end of the spindle. These spindles are continuously revolved at arelatively high speed by pinions 88 fined on the spindles and meshingwith the driving gear 48, and it will be observed that the pinions areof considerable length so that the required vertical movements of thespindles may be effected without disturbing the driv ing relationbetween the gear 48 and the pinions 83.

A can end ltlVlHg been advanced from the magazine by the shoulder 7 5 onth slide member to a position directly over the chuck head 77, as justexplained, the chuck head is now elevated carrying the can end upwardlywith it and while in elevated position the slide member is retracted.The inwardly projecting fingers 76 on the slide member are spaced apartfar enough to clea the spindle 7 8 when in raised position so that uponthe retracting movement of the slide member these lingers pass beneaththe ele vated chuck head. During the time that the shoulder is movingfrom the magazine to .7 5 with two plates .the composition applyingstation and back again, the can ends in the magazine are supportedu'aonthe slide member 54-. Each slide member is equipped adjacent theshoulder 8%, one at each side, shown in Figs. .4- to 8 inclusive, andthese plates are equipped at their forward ends with beveled surfaces 85adapted to act as separators for the can ends in the magazine. As theslide members are retracted these beveled surfaces enter between thelowermost can end in the magaz-iine and the next superposed end, and asthe membercoir tinues its retractive movement the entire stack of ends,with the exception of the lowerinostone, is lifted by the inclined.surfaces 85 in the manner shown in Fig. 7, and s rpported during theremainder of the retrartive stroke upon the plates ll hen the shoulder75 clears the magazine on the retractivestrol-re the lowermost end willdrop into horizontal alignment with the shoulder and upon reversemovement of the slide member this end will be carried to the compositionapplying station, and after the plates 84 move out from beneath thestacked ends in the magazine these ends will be supported upon the slidemember 5 1-.

While the slide member was in retracted position the chuck head 77 waslowered, thereby bringing the can end on the head into the path of theslide fingers 76, as shown at the left in Fig. l, and upon feedingmovement of the slide member this end, which has in the meantime beenoperated upon, will be advanced from the applying station to the rearend of the machine where it is delivered from the machine, as shown atthe right in Fig. 1. It will be observed that the two slide members areso connected to their respective driving gears 47 that they are operatedin alternation with the result that the ends are fed alternately fromthe two magazines and areal'ternately operated upon at the applyingstation.

The mechanism for raising and lowering the chuck spindles 7 8 is bestshown in Figs. Q'and a, fromwhich it will be observed that upon thevertical shaft 49 there is mounted a cam86. 'At each side of this camthere is pivotallymounted at 87 upon the body ofthe machine an arm 88carrying at its inner end a cam follower 89 which rides upon the cam 86.The outer end of each arm 88 is equipped with a bearing roller 91disposed directly beneath the head of a screw 92 threaded into the lowerend of the spindle 78. As the arm 88 is raised by the cam, the spindle78 is moved upwardly into the position shown at the right in Fig. 2, andwhen the lower portion of the cam trav (ls beneath the roller 89 thespindle is low cred bythe expansion spring 81. Thus it will be seen thatthe spindles and chuck heat-s are raised and lowered in alternation andin proper timed relation with the reciproeatory movements of theirrespective slide members 54. hen the chuck heads are completely loweredthey are disposed slightly below the plane of the advancing can ends, asshown in Fig.-5, so that an end may be positioned above the revolvingread by its slide member without coming in contact with the head. l/Vhenan end has been thus positioned the revolving head is elevated in themanner just described, carrying upwardly with it the positioned can endwhich is thereupon rapidly rotated with the head upon which it issupported. It is while the end is elevated and is being revolved thatthe composition is applied thereto in the groove near the periphery ofthe end and the application of the composition to the end is effected bymechanism best illustrated in Fig. 5, which will now be described.

The composition is continuously delivered from the tank to the chamber36, as has been previously explained. In the blockin which this chamberis formed there is adjustably mounted a tube 93 provided with a port 9 1registering with the chamber 36 and permitting considerable longitudinaladjustment of the tube without disturbing the registration. The outerendof the tube is closed by a plug 95 which may-beremoved to enable thetube to be cleaned. The tube is clamped in the block by clamping bolts96 (Fig. 8) and by loosening these bolts longitudinal adjustment of thetube may be accomplished. The inner end of the tube carries a verticallydisposed nozzle designated generally by reference 97, the nozzle proper98 having a small delivery orifice 99 at its lower endandbeing'removably threaded into the body of the nozzle so that it can beremoved for cleaning purposes. lVithin the nozzle body there is disposeda shut-cit valve 101 adapted toseat in the tapered nozzle tip 98 to shutoil the flow oi composition from the nozzle and this valve is normallyheld in seated position by an expansion spring 102 surrounding the valvestem 103 and bearing at its lower end upon a collar 1041 fixed to thevalve stem and its upper end against the closure 105 which is encased ina suitable packing gland 106. The upper end of the valve stem isprovided with a laterally extending slotted arm 10'? which is connected,by clamping nuts 108 to a' vertically reciprocable rod 109 mounted in abearing 111, the lower end of this-rod having a rounded head 112disppsed in axial alignment with its chuck head 7 The parts justdescribed normally assume the position shown in Fig. 5, in which thenozzle out-let is closed and no discharge of composition can take place.revolving chuck head, however, is elevated, in the manner previouslydescribed, the

When the can end is carried upwardly against the head 112 of the rod109, thereby moving this rod upwardly which, through the connected baror arm 10?, carries the valve stem 105 upwardly so as to withdraw thevalve 101 from its seat against the force of its spring 102, therebypermitting the composition to be delivered under pressure from thenozzle directly into the peripheral groove of the rapidly revolving, canend which is now in close proximity to the discharge orifice of thenozzle. The valve remains open for a pre-determined period and theapplication of the composition to the can end continues until the chuckhead is lowered, whereupon the valve is closed by the spring 102 and theflowofcomposition is shut off. Since the operation of the machine isvery rapid, it will be manifest that the valve is maintained in openposition justlong enough to deliver the requisite quantity ofcomposition to the can end where it is applied over the desired surface.

It will be obvious that the adjustable mounting of the nozzle supportingtube 93 and the slotted connection between the bar 107 and the rod 109permits the nozzle to be adjusted with a fine degree of nicety so thatthe composition is delivered at exactly the right point to the can endand thatthis.

plyin tation and the end at the station which has received itscomposition is delivcred from. the machine simultaneously by the lingers76. Upon return stroke of the feeding device the lingers 76 travelbeneath the then elevatedclmck head and the separating plates 84:separate the lowermost can end in the magazine from the remainder of thestack and this end drops into alignment with the shoulder 75, to bethereby advanced on the next advancingmovement of the slide member. Thecan end at the applying station is elevated and rapidly revolved by thechuck head and its upward movement into proximit to the applying nozzlecauses the nozzle valve to be opened so as to permit the delivery of therequisite amount of composition by the nozzle to the end. I
